Cotton towel with structural polyester reinforcement

A mostly cotton yarn terry cloth product is provided with borders having high content polyester yarns. The polyester borders are more rugged, and thus aid in preventing fraying and failure along the edges. In addition, reinforcing ribs, also formed from yarns have a high polyester content, may be provided that extend from a border on one side of the terry cloth product to a border on the other side. This feature anchors the borders in place, limiting failure at the juncture of the border and the adjacent cotton.

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of provisional application No. 61/176,831, filed on May 8, 2009, the full disclosure of which is incorporated herein by reference.

BACKGROUND

Hospitality terry cloth bathroom items, such as wash cloths, hand towels, bath mats and bath towels, are frequently made of 100% cotton for absorbency and feel. However, cotton terry cloth is inherently weak, which makes the outer edges (selvage and hemmed) prone to pre-mature failure. This failure may be due to poor construction and/or the weak characteristics of the cotton fibers.

Due to the high failure rate of the cotton terry cloth products, using 100% cotton terry cloth items in the hospitality industry creates a budgetary burden that is hard to overcome since damaged or defective towels cannot be placed in a guest room. Continued replacement of terry cloth bathroom items is expensive and wasteful. Many hotels, in order to keep their expenses in check, do not purchase sufficient inventory to service their hotels. As a result, terry items are laundered and rotated at least four times per week. Given the useful life of a terry cloth towel as an example at 50 use and laundering cycles, the calculated life of a towel is 12.5 weeks before the item needs replacing.

There is substantial expense in replacing such towels, especially for the higher quality towels, which typically provide even shorter life span. A premium quality bath towel, normally used to exhibit value to hotel customers, can cost anywhere from around US$5.00 each up to US$7.00 each. The average hotel will normally get between 20 and 25 uses out of such a premium bath towel (the most expensive piece in the bathroom ensemble). More often than not the towel has plenty of life remaining in the body, but its edges fail because of inadequate structural construction in the selvage edges or top and bottom hems. This failure can also occur in the sewn upper and lower hems.

Part of the reason for these failures is the construction technique used by the weaving mills when constructing these products. Spun cotton yarns are used almost exclusively throughout a towel used in the hospitality industry; fine combed and carded cotton, when twisted together, make a quasi-durable component in the towel manufacturing process but a single yarn can be chaffed, and broken through multiple uses. When this happens all of the remaining yarns used in the process are prone to failure as well.

Over the years some manufacturers have blended cotton with polyester in ratios of 86% cotton/14% polyester in an effort to make the terry cloth items stronger and more durable. However, many corporate hotels have resisted buying these types of towels thinking that any terry product that has any polyester in the composition would be less appealing than their 100% cotton counterparts.

BRIEF SUMMARY

The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.

In an embodiment, a terry cloth product, such as a towel, is provided, including a pile fabric having a width and a length, first and second length edges, a first set of yarns extending lengthwise and forming a first border along the first length edge, and a second border along the second length edge. A second set of yarns extends lengthwise and between the first and second borders and a third set of yarns forms a reinforcing rib extending widthwise between and into the first and second borders. The first, second, and third sets of yarns include cotton, and the second and third sets of yarns comprise a polyester fiber content higher than the first set of yarns.

In an embodiment, the polyester content of the first set of yarns is approximately 0%, and the polyester content of the second and third set of yarns is approximately 50%.

The first and second borders may be, for example, ¾ inch in width. Likewise, the reinforcing rib may be approximately ¾ inch in width. The ribs may be spaced as desired, and in an embodiment are spaced between approximately 3 and 6 inches, on center, apart from one another. Smaller width of ribs may be used when the ribs are placed closer together. In either event, the total polyester content of the towel is preferably maintained at a low amount, such as 3 to 5% of the total towel composition.

The terry cloth product may include a plurality of the reinforcing ribs comprising the set of third yarns, each of the reinforcing ribs extending between the first and second borders and being spaced from the other ribs. Each of the plurality may be formed from weft yarns.

In an embodiment, the first and second borders each have a doubled over hem. The doubled over hems for the first and second borders may be attached by two needle stitching.

The terry cloth product may also include first and second width edges, and a fourth set of yarns extending lengthwise and forming a first width border along the first width edge, and a second width border along the second width edge. The fourth sets of yarns may also include a polyester fiber content higher than the first set of yarns.

In accordance with another embodiment, a terry cloth product is provided having warp yarns, including first and second border warp yarns and middle warp yarns captured between the first and second border warp yarns, with the border warp yarns having a higher polyester content than the middle warp yarns. The product also includes weft yarns, the weft yarns including primary weft yarns, and a reinforcing rib weft yarn set, the reinforcing rib weft yarn set having primary weft yarns on each side; the reinforcing rib weft yarn set comprising yarns having a higher polyester content than the primary weft yarns.

In yet another embodiment, a terry cloth product is provided, having a cotton ground center and a high polyester content, cotton/polyester blend outer border.

In further embodiments, a method of producing a terry cloth product, including weaving a first weft yarn through warp yarns to form a high polyester content, cotton/polyester blend outer border; and weaving a second weft yarn, different from the first weft yarn, to form a cotton ground center for the terry cloth product. The method may include weaving a third weft yarn into the warp yarns, to form a high polyester content, cotton/polyester blend rib for the terry cloth product, the rib, after completion, being captured between two different layers of the second weft yarn.

For a fuller understanding of the nature and advantages of the present invention, reference should be made to the ensuing detailed description and accompanying drawings.

 DETAILED DESCRIPTION

In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.

Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows an isometric view of a terry cloth product 20 in accordance with an embodiment. As is known and as is shown in FIG. 4, terry cloth textiles or products T include three different yarn types. Warp yarns A run continuously through the terry cloth product T. Weft or filling yarns E run perpendicular to the warp yarns A, and pile yarns P are interlaced and locked into position by the warp yarns A and weft yarns E with uncut loops on both sides. Terry cloth products T are woven to absorb, wick, and hold liquids.

Returning to FIG. 1, the terry cloth product 20 may be any terry cloth product, but in an embodiment is a hospitality or institutional terry cloth bathroom item, such as a wash cloth, a hand towel, a bath mat, or a bath towel. Embodiments described herein are directed primarily to bath towels, but other products may be produced using variations in geometry and size.

As described in the background section of this disclosure, cotton is the preferred material for a terry cloth bathroom item because of its absorbency characteristics. However, cotton suffers some drawbacks, particularly with outer-edge failure, as described above. In accordance with an embodiment, as described in more detail below, a mostly cotton yarn terry cloth product is provided with borders having high content polyester yarns. The polyester borders are more rugged, and thus aid in preventing fraying and failure along the edges. In an embodiment, the warp and weft yarns at all four edges of the terry cloth product 20 have high polyester content, extending the high content polyester around the entire perimeter of the terry cloth product, although in alternate embodiments only a portion of the edges may include the high polyester content yarns.

In addition, as described below, reinforcing ribs, also formed from yarns having a high polyester content, may be provided that extend from a border on one side of the terry cloth product to a border on the other side. The ribs anchor to the borders, limiting failure at the juncture of the border and the adjacent cotton pile. The entire structure of the high polyester content ribs and borders provides structural dimensional stability for the terry cloth product.

Typically, as is known, the pile or ground of a terry cloth product is made on a loom, by interlacing weft yarns into warp yarns on the loom. Loop yarns are added during the weaving process. In the embodiment shown in FIG. 1, a weft direction is shown by the double arrow 22 and the warp direction is shown by the double arrow 24, but these directions may be swapped in alternative embodiments. A plurality of weft yarns 26 (FIG. 2) extend in the weft direction 22 and a plurality of warp yarns 28 extend in the warp direction 24. These weft and warp yarns 26, 28 are interlaced using a loom in a manner known in the art to form pile fabric 29 for the terry cloth product 20.

The weft yarns 26 include weft border yarns 30 and 32 at outer edges. The weft border yarns 30, 32 form weft borders 31, 33 at opposite ends of the terry cloth product 20. Spaced apart between the weft borders 31, 33 are a plurality of weft ribs 35 (FIG. 1) formed by weft rib yarns 34. The remainder of the weft yarns 26 are ground weft yarns 36 (FIG. 2).

The warp yarns 28 include warp border yarns 38, 40 at outer edges, and ground warp yarns 42 in between. The warp border yarns 38, 40 form warp borders 39, 41.

In accordance with an embodiment, the weft border yarns 30, 32, the weft rib yarns 34, and the warp border yarns 38, 40 are formed of a structurally stronger yarn than the ground weft yarns 36 and the ground warp yarns 42. In an embodiment, because cotton is strongly desired for terry cloth products, such as the terry cloth product 20, the ground weft yarns 36 and the ground warp yarns 42 are 100% cotton, or, at a minimum, a high content cotton that provides good feel and absorbency. A manufacturer may alter the content of the ground weft yarns 36 as desired, keeping in mind that adding polyester increases strength and reduces costs, but possibly in exchange with a loss in feel and absorbency. In an embodiment, the fiber content of the entire terry cloth product 20, including the borders and the ribs, is 95 to 97 percent cotton.

In an embodiment, the weft border yarns 30, 32, and the warp border yarns 38, 40 are formed of structurally stronger yarns than the ground weft and ground warp yarns 36, 42. Typically, when terry cloth products, such as the terry cloth product 20, are laundered, the edges and hems are subjected to an inordinate amount of friction and abrasion, resulting in processing damage and failure. To alleviate this problem, in accordance with an embodiment, structurally strong, such as high polyester content, yarns, are used along the selvage (side or warp) edges (i.e., for the warp border yarns 38, 40), as well as the fill (weft or end hem) edges (i.e., for the weft border yarns 30, 32). This construction permits the terry cloth product 20 to better survive the laundering process, primarily by limiting edge fraying or failure. If desired, this feature may be provided on just the selvage edges, only the fill edges, or both.

Similarly, the weft rib yarns 34 are structurally stronger than the ground weft and ground warp yarns 36, 42. As such, as described below, the weft ribs 35 provide structural strength and dimensional stability for the terry cloth product 20.

In an embodiment, the weft border yarns 30, 32, the weft rib yarns 34, and the warp border yarns 38, 40 are, for example, cotton/polyester blended yarns, with high polyester content. As an example, the yarns used in these areas may include 35% to 50% polyester content, and, more preferably, 50% polyester content. The content of the fibers of the weft border yarns 30, 32, the weft rib yarns 34, and the warp border yarns 38, 40 do not have to be identical, but in an embodiment, the three areas use yarns having the same content.

In an embodiment, pile yarns 46 for the terry cloth product 20 are formed of 100% cotton. This feature permits the rougher polyester rib and border yarns to be imbedded under or twisted within the cotton surface provided by the pile yarns.

The number of weft rib yarns 34 may be selected to provide a desired thickness for the weft ribs 35. Generally, the number of weft rib yarns 34 is selected so that the weft ribs 35 provide dimensional stability and structural strength for the terry cloth product 20. In an embodiment, the weft ribs 35 are between ½ and ¾ inches each in thickness, and preferably three quarters (¾) of an inch in thickness.

The weft ribs 35 are preferably spaced so that they provide dimensional stability and structural strength for the terry cloth product 20, while minimizing the amount of non-cotton yarns in the terry cloth product. In an embodiment, where three quarter (¾) inch ribs 34 are utilized on a full sized bath towel, for example 24 inches by 48 inches, the weft ribs are spaced three (3) to seven (7) inches on center, and more preferably six and one half inches on center. Different dimensions may be used, based upon the size of the terry cloth product 20, and the width of each of the weft ribs 34. In an embodiment, for smaller terry cloth products, such as a washcloth, no ribs, or a single small rib, may be provided.

In accordance with an embodiment, the borders 31, 33, 39, 41 formed by the four border yarns 30, 32, 38, and 40 are sewn rather than tucked or formed into blown selvage. The borders 31, 33, 39, 41 are each sewn into a hem, such as is shown in FIG. 2. FIG. 2 shows a hem 48 being formed in a first step along the border 31, and FIG. 3 shows a second step of adding a second hem 49 along the border 41. The hems 48, 49 may be provided on all borders, or any subset of the borders.

As shown in FIG. 2, and in accordance with an embodiment, the hem 48 includes hem yarns 50 along the lower surface, a first fold line 52, and a second fold line 54. This doubled-over hem 48 provides an advantage in that the end edges of the terry cloth product 20 are not exposed, but instead are wrapped inside the doubled-over hem.

In accordance with an embodiment, a double needle, or two needle, sewing machine is utilized to provide double stitching 56 of the doubled-over hem 48. The double stitching 56 provides two stitches instead of the conventional single stitch model, providing a backup stitch in case of failure. Very often, during a laundering process, bleach is used to remove residual stains. Residual bleach left in a towel or other terry cloth product during a laundering process can disintegrate a single yarn. Thus, utilizing two needle construction and the double stitch 56 as shown in FIG. 2 provides a more stable hem 48. The hem 49 is preferably formed in the same manner, first being doubled over, and then doubled stitched. Furthermore, in addition to two-needle stitching, the type of stitching may be altered to a particular product. Any of several stitch types can be used to hold the seams together; straight-stitch, lockstitch, zig-zag, chain-stitch, overlock stitch or blind-stitch.

Example

An example of a terry cloth product, such as the terry cloth product 20, formed in accordance with an embodiment herein, is now described. The example is for a towel for use in the hospitality industry (for example, 24 inches by 48 inches). For this particular example, three different yarns are used. The yarns described below are examples, and variations in content, twists per inch, and amount used could be provided in accordance with embodiments described herein.

    • The weft borders 31, 33, the weft ribs 35, and the warp borders 39, 41: a 50% cotton/50% polyester yarn with 15 twists per inch is used to provide structural integrity for the edges of the terry cloth product and for the reinforcing ribs 35.
    • The ground weft yarns 36 and the ground warp yarns 42: a 100% single ply cotton yarn with 15 twists per inch is used in all other warp and weft fill directions except for the ¾″ reinforcing ribs which shall be the 50% polyester and 50% cotton yarns.
    • The pile yarns 46: a 100% single ply cotton yarn with 15 twists per inch is used for the pile yarns.

Looms (not shown, but known) are set up so that the warp yarns 38, 40 along each of the edges are woven with the 50% cotton/50% polyester yarns. These warp yarns 38, 40 form the warp borders 39, 41. The rest of the warp yarns (i.e., the ground warp yarns 42) are the 100% cotton single ply cotton yarns with the 17 twists per inch.

The weft yarns are interwoven into the warp yarns, with an initial three quarter (¾) inch wide band of weft border yarns 30 for one of the weft borders 31, followed by the cotton ground weft yarns 36. Thus, the source of weft yarns should be changed during the weaving process. The reinforcing bands or weft rib yarns 34 are interwoven at between approximately 3 inches and 6 inches off center from one another, ¾ inch in width. Each time a change is made from border to ground, ground to rib, rib to ground, or ground to border, the source of weft yarns is changed. During the weaving process, the pile yarns 46 are woven into the pile fabric.

After the pile fabric has been woven, the terry cloth product 20 is cut to length and width. The areas along the warp borders 38, 40 are then doubled over and sewn, using a two needle sewing machine to fix the hems 48. The weft borders 31, 33 are then doubled over to create similar hems, also with double stitches 56.

In addition to protecting the selvage, the warp borders 39, 41 are anchored to the ends of the weft ribs 34. The doubled-over hems 48 provide an interlocking connection between the weft ribs 35 and the warp borders 39, 41, providing a structural network for dimensional stability and structural strength of the terry cloth product 20.

If desired, support ribs may be provided in the warp direction. However, the weft ribs 35 are arranged to minimize the typical shrinkage and border issues in a terry cloth product. Usually, there are twice as many yarns in a warp direction as there are in a weft direction. Warp yarns may be arranged very tightly on the warp beam (not shown, but known in the loom art) and, after being removed from the loom, even after many washes, there is not much shrinkage in the weft direction because of the tightness of the warp yarns. However, weft yarns, which are pulled through the loom, are not pulled as tightly together. Thus, there can be much shrinkage in the warp direction. This shrinkage can often result in distortion at the edges and/or dimensional instability in the warp direction due to uneven shrinkage. The warp borders 39, 41 aid in preventing fraying at the edges, and the weft ribs 35 prevent the warp borders 39 from releasing from the edges, and provide dimensional stability across the weft direction. If the edges were reinforced with only the warp borders 38, 40, these warp borders may release as a result of shrinkage and wear of the terry cloth product in the area adjacent to the warp borders. The weft ribs 34 provide structural support and strength in the weft direction and dimensional stability, and help to anchor the warp borders 38, 40 in place. To this end, the spacing of the weft ribs 35 may be selected to properly balance the goals of properly anchoring the warp borders and maximizing the amount of cotton used in the terry cloth product. In addition, as described above, the terry cloth product may be formed so that the total cotton content of the product may meet a desired goal, such as 95 to 97 percent cotton.

Testing by an independent testing agency was obtained and is included at Appendix A. Towels utilizing the structures herein passed all standard towel tests.

In addition to the testing at Appendix A, towels were used over the course of a month, and an evaluation of towels formed in accordance with the specifications for Example 1 were found to have no quality, overall performance, processing, or guest reported issues. Drying time was slightly down compared to 100% cotton towels, selvage edges were not frayed, and soil and stain removal were improved. Comments on the towels were positive, and estimates were that linen life should be increased, and cost should be significantly reduced.
